Answer:
It's fair value at the date of the transfer
Explanation:
Transfers of securities between categories of investments should be accounted for at FAIR VALUE, with unrealized holding gains or losses treated in accordance with the nature of the transfer.
Available-for-sale securities are reported at fair value; changes in value between accounting periods are included in accumulated other comprehensive income in the equity section of the balance sheet.
The fair value option gives companies the option to report most financial instruments at fair value with all gains and losses related to changes in fair value reported in the income statement.
